RADIATION IMAGING USING SIMULTANEOUS EMISSION AND TRANSMISSION

摘要

A gamma camera (70), comprising: at least one emission detector (72), which receives radiation emitted from the body of a subject (26) and generates signals responsive thereto; a radiation source (74), which directs radiation toward the body; at least one transmission detector (76), having a long dimension, which receives radiation transmitted through the body (26) from the radiation source (74) and generates signals responsive thereto, wherein the transmission detector (76) translates in a direction generally perpendicular to the long dimension.
